MULE AND TWINEE FOR SPINNING YARN.

Specification of Letters Patent.

Serial No. QOLQQO.

To all whom it may concern:

Be it known that I, PHILIP BRUoE WHITE- HEAD, British subject, andresident of Stockport, county of Chester, England, mill manager, haveinvented certain new and useful Improvements in Mules and Twiners forSpinning Yarn, of which the following is a specification.

In all makes of self-acting mules when the backing off commences thereis a moment before the faller Wires get control of the thread in whichthe yarn is permitted to become slack allowing it to run into snarlswhich are a serious drawback to its quality. This arises partly owing tothe backing oz'f chain being kept a little slack for fear of the fallerwire overtaking the yarn too soon and breaking the ends.

The object of the present invention is to prevent the yarn becomingslack at the moment backing of commences.

It consists essentially of an arrangement for connecting and working thefallers to permit the counter faller being raised against the yarn toput tension thereon immediately before backing off in advance of andwithout giving a corresponding movement to the winding faller, therebypreventing the yarn becoming slack.

The invention will be fully described with reference to the accompanyingdrawings forming part of the specification in which sufficient of a selfacting mule is shown to illustrate the invention.

Figure 1. front elevation of part of mule carriage and head stock. Fig.2. side elevation partly in section on line :cx. Fig. 3. side elevationpartly in section on line yy.

The headstock A the carriage B, the wind ing faller C, the counterfaller D and the backing ofi rod E and the mechanism for working theseparts not shown in the drawings are all of any ordinary construction andoperated in the usual way.

In addition to the usual mechanism by which the winding faller C isdepressed to a point just above the yarn and the counter faller D raisedto a point just under the yarn when the carriage B is at the head orposition farthest from the rollers and before the backing off movementcommences (the position shown in the drawings) I employ means to give anadditional movement to and further raise the counter faller wire D untilit rests against the under side of threads or ends of yarn W and pressesthem upward Y against the winding faller wire C w rich prevents the endsbeing drawn the spindle point thereby putting a tension upon the yarn asthe backing off commences. The counter faller D is connected in theusual way by the connecting link (25 with the weighted lever D pivotedto the under side of the carriage B and this in turn is connected bychain (Z to the l ver C and connecting link 0 with the winding faller Cso that the movement of the one is complementary to the other. I nowintroduce a supplementary motion between the connecting links a and d bywhich the weighted lever 15 which controls the counter faller D ispermitted to move in advance of the winding faller C and its link 0, andthe counter faller D is thereby raised slightly before the movement ofthe winding faller G for backing of? On the lever C, pivoted to thefront of the carriage B a sliding block F is mounted to which theconnecting link 0 of the winding faller O is connected instead of to aneye or eye bolt made fast to the lever C. As the lever C is in normalposition, set somewhat on an incline it follows that if the block F ismoved toward the free end that the lever will fall slightly withoutdrawing down the link 0. This movement allows the counter faller lever Dto fall thereby raising the counter faller D, without giving acorresponding downward movement to the winding faller C. The counterfaller is weighted and operated in the usual way during the run-in ofthe mule carriage. The sliding block F on the lever C is connected withthe backing off rod E by a wire rope or band G latches H H the pulleys KK and bands is It; as soon therefore as the backing olf lever E beginsto move, the slide block F is moved and the desired supplementarymovement given to the counter faller D. The block F is drawn back tonormal position by a spring such as M.

As the head stock A to which the backing off rod E is pivoted isstationary and the carriage B runs backward and forward a sliding latchH to which the band G is connected is mounted upon the carriage and asliding latch H to which the band 7c is connected is mounted upon theheadstock. The latches H H are of hooked or other shape as to engagewith one another (see Fig. 1) each time the carriage travels outward anddisengages when the carriage travels inward again. A spring forces thelatch downward after it has been lifted by the backing off rod E.

headstock or on the floor bracket or other- It will be evident that inany other make I of mule the connection between the taller and countertaller levers may be made in any convenient way to permit of the countertaller I lever moving downward before the backing oit movement of thewinding taller Cbegins and also that the necessary connection with apart of the mule that moves in advance of the backing otf may be made inany convenient manner. The connection may be made with i such parts ofthe mule as the strap tork, a spring or other device connected with orreleased by the twist wheel, or with a bowl or runner working upon anincline upon the wise.

hat I claim as my invention and desire to protect by Letters Patentis 1. In a mule or twiner the combination with the headstock A, thecarriage B, the winding taller C, the counter taller I), and the backing0ft rod E, of a sliding block on the counter taller lever and means tormoving it on the lever interposedbetween the winding taller and thecounter taller, and connected with an operative part of the mule whichmoves before the backing oft commences, by which the counter taller israised against the yarn to put a tension upon it immediately beforebacking cit and in ad vance ot the movement of the winding taller torbacking oft substantially as described.

2. In a mule or twiner the combination With the headstock A, thecarriage B, the winding taller C, the counter taller D, and the backingott rod E, of a sliding block 011 the counter taller lever and means formoving it thereon whereby the connection between the winding taller andthe counter taller is lengthened when the carriage is at the head toraise the counter taller against 3. In a mule or twiner the combinationwith the headstock A, the carriage B, the Winding taller C, the countertaller D, and the backing cit rod E, the winding taller lever C andconnecting link c of a block F capable of sliding on the lever C towhich the connecting link a is connected and means by which the slidingblock is moved before backing ott commences substantially as described.

4. In a mule or twiner the combination with the headstock A, thecarriage B, the winding taller C, the counter taller D, and the backingoft rod E, the connecting link c and the winding taller lever C of ablock F moving thereon, a band G connected thereto and to an operativepart of the mule, substantially as described.

5. In a-"mule or twiner the combination with the headstock A, thecarriage B, the

winding taller C, the counter taller D, and

the backing oft rod E, the connecting link .0 and the winding tallerlever C of a block F moving thereon a band G connected thereto, a latchH on the mule carriage, a latch H on the mule headstock, a band Itconnectedtom the latch H, pulleys K K and a band Zr connected to thebacking ott rod E by which the movement of the rod is transmitted to thesliding block F substantially as described.

In witness whereot I have hereunto signed 5 my name in the presence oftwo subscribing witnesses.
